FEATHERWEIGHT' PIPE Application filed May 22, 1931. Serial No. 539,325.

The present invention relates broadly to improvements in a pipeconstruction and more particularly to means for conducting and radiatingexcessive heat originating within the bowl of ametal pipe of lightweight.

Hitherto metal pipe bowls were partially provided with an increasedradiating surface in the form of spatially arranged annular 1O fins. Thepurpose of the fins was to drive off the heat from the outer surfaces ofthe bowl transmitted from the inside by conduction. In actual practice,however, it has been found that such a construction although radiatingsome heat failed to provide a coo smoke with the result that hot fumeswould be conducted through the pipe stem to the user.

To overcome this disadvantage the stem :9 of the pipe was provided witha plurality of fins to increase the surface radiating characteristicsthereof and even with this supplemental radiating surface of the pipe,if'

used, did not produce a cool smoke.

Accordingly, one of the objects of the present invention resides in theprovision I of means for producing a cool'smoke with a metal pipewithout anydeleterious effects to the user.

Specifically,

39 another object is to provide a metal pipe of light weight having thebowl,

the stem and the portion of the stem providing a seat for the bowl eachconstituted with supplementary radiating means. Still another aspect ofthe invention and an advantage thereof contemplates means to radiate anddisperse heat from the hottest part of the bowl.

A further aspect is to provide a pipe bowl with closely spaced fins orribs'extending exclusively the entire height thereof and a stem forsupporting the bowl with closely spaced fins or ribs extendingsubstantially the en-' tire length thereof. r I

How all the above features of my invention are carried into effect Willbe best understood from the following specific description in detail ofa preferred embodiment and although such preferred embodiment isexplained merely as illustrative of the inven tion and is not considereda limitation there- .on, the invention will be best understood from aconsideration ofsuch specific procedure. To aid the following specificdescription of the construction and principles of my invention, I referto the accompanying drawing in which.

Fig. 1 is a side view in elevation of my improved pipe construction.

Fig. 2 is a front view thereof. "Fig. 3 is a sectional view taken alongthe line 3-3, Fig. 2 in the direction of the arrows.

Fig. 4 is a longitudinal sectional view along 1 the line 44, Fig. 3 inthe direction of the trated, the bowl may include any other suit- Y ablecorrugated surfaces to increase its radiating capacity as is wellunderstood.

Depending from the bottom wall 13 of the bowl and preferably castintegral therewith is the tube or neck portion 14 provided with theaxially disposed bore or channel 15 which communicates with thedepression or pocket Providing a seat for the tube 14 concomitantlysupporting the bowl is the elongated stem generally denoted 16,preferably cast as a. single member, of light metal, aluminum or thelike and is provided, as illustrated, with the closely and spatiallyarranged ribs or fins 16 extending substantially the entire length ofthe stem to increase the heat radiatin g capacity thereof.

The seat portion 17 of the stem is enlarged and embodies fins as 18 and19 of a'diameter greater than the fins 16' but extend substantially inparallel relation therewith. Furv v i 5 fins.18 and 20 and radiallyextending from the enlarged seat portion although integral therewith isthe pair of spaced fins 2S and 24. Associated with the bowl seat portion17 is an opening25, the sides thereof being suitabl connected man or gastight fashion wit the exterior surfaces of the tube 14, in a manner Wellunderstood in the art, but, however, in such relation that the openingof the seat is in communication with bore l5 andthe channel 21 of thestem.

Spaced from the last fin 26 which is si1ni vlar in allrespects as thefins 16' is the annular stop flange 27 from which extends the tubularnipple 28 providing means to sustain the mouth piece or holder 29 whichmay be connected to the nipple 'in any well known manner incommunicating relationship.

Preferably,the seat for .the bowl, the stem, the flange and nipplethereof are cast in one 26 piece, although, the invention is not limitedf in this respect-as these parts may be separable and suitably fastenedtogether.

. Generally the hottest part-of the bowl. is along the lower facesthereof .and within .18 close proximity to the bottom wall 13. As

pointed out, it is desired to disperse this heat to lower thetemperature of the fumes originally developed by puifing'on the holder29 andthereby produce a cool and sweet smoke. To this end, it isapparent that the heat on wall 13 or adjacent thereto, is conducted totheneck portion 14 and therefrom transmitted to the seat 17 and theenlarged fins as 18, 19, 20, 23 and 24. heat at the hottest portion ofthe bowl .is 1 widely distributed and dispersed at its-source I and thisaction is supplemented by the radiating fins 16 of the stem, which tendsto progressively and further widely distribute any heat of the fumes notdiffused by the finsof the bowl seat or by the fins 12 of. the bowl.Stated in another way a supplementary radiating surface is provided fromthe upper plane of the'bowl to the remote end of the stem sustaining theholder. Thus a progressive and continuous heat radiating surfaces isprovided although said surfaces are disposed on separate parts. 7

As many changes may be made in the above construction and manyapparently widely different embodiments of the invention could bedevised without departing. from the scope thereof, it is intended thatall matt'er'contained in the above description or shown in theaccompanying drawing shall be inter preted as illustrative and not in alimiting sense. i

I claim:

86 having an outside corrugated surface, a stem -In this way, the

connected tothe bowl havin an outside corrugated surface, a seat prov]ed on said stem for said bowl and 1n alinement therewith operative toradiate and 'a stem inclu ing a seat for said bowl, said fins radiatingtherefrom.

3.-As an article of manufacture, a pipe having a bowl embodying spacedannular fins extending the entire height thereofyan enseat' comprisingan enlarged portion having larged stem having a plurality of spaced finsand comprising a seat for the bowl, said seat v having fins the bowl.

4. As an article of manufacture, a pipe having a bowl,'a stem connectedto the'ibowl, a

holder sustained by said stem, a seat for the bowl at one end ofthestem, the bowl,

juxtaposed with oneportion of seat and stem having spaced fins, thelatterbeing disposed continuouslyfrom the upper plane of the bowl andadjacent to a remote extremity of the stem. I 5. As an article ofmanufacture, a pipe having a. bowl, a stem connected tothe bowl and incommunication therewith, a holder sustained by said stem, an enlargedportion providing a seat for said bowl at one end of the stem, the bowl,seat and stem having closely spaced fins, the latter extendingcontinuously from the upperplane of the bowl to one extremity of thestem.

6. As an article'of manufacture, a pipe with a bowl having a finnedsurface, a stem connected to the bowl also having a finned surface, aseat for the bowl'at one end of the stem having a finned surface, thefins of said seat extending laterally and radially thereof. 7. As anarticle of manufacture, a pipe with a bowl having a closely finnedsurface, a stem;

also having a closely finned surface, a seat for the bowl at one end ofthe stem having a closelyfinned surface below and in alinement with thebowl, the

fins of said seat extending radially, laterally and transverselythereof.
